suchfor instance as a stone. By providing the cleyisoonnections 12 itwillbe seen that the line of draft be varied when animals are hitched to the singletrees 14:, carried the doubletree' 15:, which double/tree is con nested through the medium of a link 16 to the cross bar 13, thereby allowing the amount of pressure exerted downwardly on the roller 5to be yaried according to thenatuire of'the groundbeing worked.

The draft is varied by shifting the clevis' pins downwardly or upwardly and passing the same through any of the apertures 18 in the forward ends of the arms 9. l Vhen the pinsare shifted downwardly,'it will be seen that the line of draft will be so shifted that increased pressure will beeXerted down wardly onthe roller-5 and when the pins 1'? areshifted upwardly. it will be seen that the pressurewillbe reduced. V a

From the above'it will be seen that'a pul- Verizer androller provided which is so construeted; that the use of springs or Weights for holding down the rearwardly dispesed roller is elii'ninated and that the draft of the animals is utilized for forcing the, rearwardly disposed rollers downwardly into engagement with the ground." Also that moyesbver the ground.

- roller "being carried by re'arwa rdly sat -mt;

the downward pressure of the roller may be varied and that saidrollermay tilt as it -The frame is provided with a conven tional form of tongueiltl, to the forward end animals be hitched in the of which the usual 7 manner.

QThe invention haying beenlset' forth what is claimed asnew and useful is: p

The combination with aland roller, of

anauXiIiaryrOlIer trailed thereby said auxiliai'y roller being pivotally mounted to the rear ends of arms extending forwardly of the land roller, said forwardlyv extending arms being 'pivotally "mounted to the land roller at points intermediate their lengths,

and 'means whereby draft means may be connected to the forward ends of said arms and utilized for propelling theroller and 6X rting a downward pressure on 'the auxllilfd'ry I'Oller. r I i v "2'. r a combination with a inn roller comprising a framehaving a roller mounted therein, of an auxiliary roller; disposed behind thefralne carr ed "roller, saidjauxiliary ing arms 'piyotajlly mounted on 1 the roller frame, 'said rearwardly e itenchng arms hav- I farwataiy extending portions terminating in olevlses and means wherebydraft thfailxiliary 'rsuer.

of'the frame carried roller, means whereby draft means may be hitched to the forward mounted forwardly extending arms-,means whereby said auxiliary roller maytiltverti: cally longitudinally, means whereby draft means may be hitched to the forward ends of said forwardly extending arms and utilized fondrawing the roller and exerting:

downward pressure on the auxiliary roller and means whereby the downwardpr'essui'e on the auxiliary roller may be varied,
